Chemical Structure

2,3-Dibromo-4-(difluoromethoxy)benzoic acid CAS 1804882-12-9 chemical structure

Description

The occurrence of 2,3-Dibromo-4-(difluoromethoxy)benzoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,3-Dibromo-4-(difluoromethoxy)benzoic acid (CAS 1804882-12-9), molecular formula C8H4Br2F2O3 and molecular weight 345.92 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,3-Dibromo-4-(difluoromethoxy)benzoic acid (C8H4Br2F2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 2,3-Dibromo-4-(difluoromethoxy)benzoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
